. HPE supports these utilities
on all MC990 X platforms.
hubstats
command
The
hubstats
command monitors NUMAlink traffic, directory cache operations, and global reference
unit (GRU) traffic statistics on MC990 X systems. It is useful as a performance monitoring tool and as a
tool to help you to diagnose and identify faulty hardware. The
uvstats
library supplies the
hubstats
command with statistics from the MC990 X dashboard.
linkstat
command
The
linkstat
command monitors NUMAlink traffic on MC990 X systems. The
linkstat
command
returns information about packets and Mbytes sent/received on each NUMAlink in the system. It is useful
as a performance monitoring tool and as a tool to help you to diagnose and identify faulty hardware. The
uvstats
library supplies the
linkstat
command with statistics from the MC990 X dashboard.
gr_systat
command
The
gr_systat
command monitors CPU and memory activity on x86 systems. It’s graphical output
display includes information about CPU utilization, I/O wait times, IRQs, and memory utilization, both for
the system as a whole and for each node. The
gr_systat
command is a useful performance monitoring
tool.
nodeinfo
command
nodeinfo
is a tool for monitoring per-node NUMA memory statistics on MC990 X systems. The
nodeinfo
tool reads
/sys/devices/system/node/*/meminfo
and
/sys/devices/system/
node/*/numastat
on the local system to gather NUMA memory statistics.
Sample memory statistics from the
nodeinfo
command are:
